Gearboxes

Gearboxes are designed to reduce or increase a specific input speed and corresponding output speed/torque. They accomplish this through a set of gears, and stages of gears. Usually, the gearbox when used with both AC and DC motors are selected to only one specific output ratio. The ratio reductions can be from 1000:1 to 2:1 and are application specific.

Because gears are used to accomplished the speed and torque changes it is important to consider the material composition of the gear design (steel, aluminum, bronze, plastic) and the type of tooth configuration (bevel, helical, spur, worm, planetary). All these considerations must define for the gearbox to operate efficiently and maintain longevity and quietness.

Typically, most gear boxes are either oil filled or grease filled to provide lubrication and cooling. It is common for larger gear boxes that are filled with oil to have a “breather vent” since as the oil heats up and the air expands inside, the air must be released or the box will leak oil.

Sizing a gear box for a specific application is a straight forward process. Most manufacturers of gear boxes have compiled data for ratios, torque, efficiency and mechanical configurations from which to choose from.
